Sized at 28 mm, the Oystersteel case is built around a monobloc middle case with a screw-down case back and screw-down winding crown featuring Rolex's Twinlock double waterproofness system, delivering water resistance to 100 metres. A domed bezel and scratch-resistant sapphire crystal complete the case, while the Chromalight display on the lavender dial provides highly legible hands and markers with long-lasting blue luminescence.
Power comes from Calibre 2232, a perpetual, mechanical, self-winding movement of Manufacture Rolex. The oscillator relies on a Syloxi silicon hairspring with patented geometry and high-performance Paraflex shock absorbers, with bidirectional winding via a Perpetual rotor. The movement delivers a precision of -2/+2 seconds per day after casing and a power reserve of approximately 55 hours, earning Superlative Chronometer certification — encompassing both COSC testing and Rolex's own post-casing verification.
The three-piece solid-link Oyster bracelet in Oystersteel secures via a folding Oysterclasp fitted with an Easylink 5 mm comfort extension link, allowing on-the-fly sizing adjustments for a consistently comfortable fit throughout the day.
